IMPROVEMENT IN CAPS FOR AERATED-LIQUID BOTTLES.

Specification forming part of Letters Patent No. 175,952, dated April11, 1876 application filed April 19, 1875.

To all whom it may concern:

Be it known that I, JOHN EDWARDS, of Hull, in the county of York,England, professor of music, have invented an Improved Bottle and Gapfor Aerated Liquids, of which the following is a specification:

This invention relates to bottles and caps for containing aeratedbeverages to be used with internal stoppers; and consists in formi n gthe cap of a piece of india-rubber or gum tube, fitted into the neck ofthe bottle, such tube being held in position, preferably, by a brassretaining-piece, secured to the neck of the bottle by being bent over afillet on the neck.

To prevent the aerated beverage from coming into contact with the brassretainingpiece, and also to more effectually secure the rubber, I makeuse of a block-tin or whitemetal mouth-piece.

Figure l is a longitudinal section of a bottle constructed under myinvention. a, recess or chamber for retaining the internal stopper 1)when pouring out the liquid.

Fig. 2 is a plan view, and Fig. 3 a section, showing my improved capattached to the neck of a bottle. 0, piece of india-rubber or gum tubekept in position by the brass retaining-piece d; e, block-tinmouth-piece. The brass retaining-piece dis held in position by beingbent over the filletf on the neck of the bottle; b, internal stopper.

Fig. 4 is a plan view, and Fig. 5 a section, showing another cap undermy invention. 0, india-rubber or gum tube; 01, brass retainingpiece,held in position by the arms g and band 72.; e, block-tin mouth-piece;1), internal stopper.

It will be obvious that if the number of arms were increased the-bandmight be dispensed with. The stopper b is held against 0 by the internalpressure of the gases in the beverage, and so efi'ectively seals theopen- 111g.

The retaining and mouth pieces may be made of one piece of white-metalor blocktin when the bottle or vessel is filled at a low pressure.

Having now described and illustrated the nature of my invention, Iclaim- 1. The combination of the tube 0, pieces d and e, substantiallyas described.

2. The combination of the tube 0, pieces d and 6, arms g, and band h,substantially as described.
